It has a touchscreen, two joysticks and two touchpad likes surfaces, you can configure them how you like.

However the screen is 7 inches and text in games like this or early Fallouts is too small for me, so I planned to use SD for them but resigned.

There are capacitive touchpads on both sides of the deck, but calling them that really sells them short. It has an extensive controller mapping system. I play a lot of strategy and RTS games, and they can be set up with a wide variety of customizable overlays and haptics, that you can mix with button-chording as desired

Most of the Infinity Engine games play very well on a Windows tablet with an active stylus.

Unfortunately, PST is an early iteration of the engine and I had problems with inventory manipulation --- not sure if that was ever addressed.
